BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a hair cleansing composition and morespecifically to a hair cleansing composition containing a large quantityof a liquid oil, and has an excellent detergency against polymers suchas a high-viscosity silicone compound contained in hair-care products,against scum and sparingly soluble, aged sebum dirts, and provides goodfeeling upon use.

2. Description of the Background Art:

Hair cleansers are used to remove dirts from the scalp and hair fibersto keep them clean and to normalize the physiological action thereof tomaintain the health of the scalp as well as to make the hair fibersbeautiful. They contain, as primary active ingredients, anionic,amphoteric and/or nonionic surfactants. Recently, in order to reducefriction and irritation which may be encountered in shampooing and toavoid excessive defatting caused by an increased frequency ofshampooing, low-irritative detergent surfactants and various kinds ofconditioners such as polymers have come to be incorporated into haircleansing compositions.

Meanwhile, high-viscosity silicones and anti-moisture setting polymersare usually incorporated into hair-care products to improve theirfunctions. However, they are difficult to be removed by conventionlshampoos.

Insufficient removal of these polymers and sebaceous matters from thescalp and hair fibers is liable to cause various troubles such as lostof hair gloss, the split hair, dry and rough hair fibers, lack ofsmoothness, less elasticity, difficult hair styling and trangling of thehair.

Accordingly, there has been desired hair cleansing compositions whichare mild to the scalp and hair fibers and can readily removehigh-viscosity silicones and sebum dirts which are difficult to beremoved by conventional shampoos.

Under such circumstances, extensive studies made by the presentinventors have resulted in finding that a hair cleansing compositioncomprising aqueous components which are a surfactant, an alcohol andwater and oil components which include a liquid oil having a lowerviscosity than that of the aqueous components is mild to the scalp andhair fibers and can readily remove high-viscosity silicones and sebumdirts which are difficult to be removed by conventional shampoos andthat it provides good feeling upon use and has excellent stability.Further, the inventors have found that a hair cleansing compositioncomprising a branched monoalkyl phosphate and another surfactant incombination as a surfactant; alcohol; water; and silicone oil as aliquid oil can easily remove high-viscosity silicone compounds and ismild to the scalp and hair fibers.

SUMMARY OF THE INVENTION

An object of this invention is to provide a hair cleansing compositioncontaining the following components (a) to (d):

(a) : 0.05 to 15% by weight of a surfactant,

(b) : 0.5 to 40% by weight of an alcohol,

(c) : 0.1 to 25% by weight of water, and

(d) : 20 to 98% by weight of a liquid oil,

a viscosity ratio of a mixture consisting of said components (a), (b)and (c) to a mixture of oil components comprising component (d) being 1or more.

DETAILED DESCRIPTION OF THE INVNETION AND PREFFERED EMBODIMENTS

In this specification, the term "hair cleanser" or "hair cleansingcomposition" broadly encompasses not only ordinary shampoos in aclassical sense, but also preshampoos, hair-make removers, dandruffremovers, hair conditioners and the like.

Furthermore, the term "oil component" means not only the liquid oildefined as component (d) but also any other cosmetically acceptable oilsand fats and oil-soluble polymers which are optionally and generallyadopted in this technical field. A mixture of the oil componentsdesirably has a viscosity of 100 cs or less at 25° C.

Examples of the surfactant of component (a) are nonionic surfactantssuch as monoglycerides, sorbitan fatty acid esters, sucrose fatty acidesters, polyglycerol fatty acid esters, alkanol amides, amine oxides,polyoxyethylene alkyl ethers, polyethylene glycol fatty acid esters,polyoxyethylene sorbitan fatty acid esters, Pluronic, polyoxyethyleneglycerol fatty acid monoesters, polyoxyethylene propylene glycol fattyacid monoesters, polyoxyethylene hydrogenated caster oils,polyoxyethylene fatty acid amides, polyoxyethylene alkylamines and alkylsaccharides; anionic surfactants such as alkyl sulfates, alkyl ethersulfates, fatty acid soaps, ether carboxylic acids and salts thereof,alkane sulfonic acid salts, α-olefin sulfonic acid salts, sulfonic acidsalts of higher fatty acid esters, dialkyl sulfosuccinates, monoalkylsulfosuccinates, polyoxyethylene monoalkyl sulfosuccinate, sulfonic acidsalts of higher fatty acid amides, sulfuric acid ester salts of glycerolfatty acid esters, sulfuric acid ester salts of higher fatty acidalkylolamides, acylated amino acid salt and monoalkyl phosphates;cationic surfactants such as alkyl trimethyl ammonium salts, dialkyldimethyl ammonium salts, alkyl dimethyl benzyl ammonium salts, alkylpyridinium salts and alkyl isoquinolinium salts; and amphotericsurfactants such as imidazoline type, amido amino acid salts, alkylbetain type, and alkyl sulfobetain type. These surfactants of component(a) are used solely or in combination and incorporated by 0. 05 to 15%by weight (hereinafter referred to as %), preferably 0.1 to 5% based onthe total composition.

Examples of the alcohols of component (b) are monoalcohols such asethanol; and polyols such as glycerol, ethylene glycol, diethyleneglycol, triethylene glycol, hexanediol, butylene glycol, heptanediol,propylene glycol, sorbitol, maltitol, and polyethylene glycol. Of them,especially preferred are ethanol, glycerol, propylene glycol, butyleneglycol, sorbitol, and polyethylene glycol.

These alcohols are used solely or in combination, and incorporated by0.5 to 40%, preferably 2 to 30% based on the total composition.

The water which is component (c) is incorporated by 0.1 to 25%, morepreferably 1 to 15%, based on the total composition.

The liquid oil of component (d) is not limited as far as it is liquid at25° C. Examples thereof are 4 and 5-membered volatile cyclic siliconecompounds, dimethyl polysiloxane of 100 cs or less, methyl phenylpolysiloxane of 100 cs or less, squalane, hydrocarbons such as liquidparaffin and isoparaffin, branched fatty acid, higher fatty acid esters,benzoates, triglycerides, diglycerides, and rosin derivatives. Of them,more preferred are cyclic silicone compounds, dimethyl polysiloxane andmethyl phenyl polysiloxane of 20 cs or less, isoparaffin of 20 cs orless, fatty acid alcohol ester, diglycerides and triglycerides. Here,"liquid at 25° C." in this invention is determined as follows: In aflat-bottom test tube (inner diameter: 30 mm, height: 120 mm) havingbench marks at the heights of 55 mm (A) and 85 mm (B) from the bottom, asample is placed to the level of mark A. The test tube is bathed in 25°C. water for more than 10 minutes and then, it is laid down on ahorizontal plate. Samples which reach mark B within 90 seconds are takenas "liquid at 25° C.".

These oils are used solely or in combination, and incorporated by 20 to98%, preferably 50 to 98% based on the total composition.

In this invention, oil components containing component (d) are keptstable as an O/W emulsion. It is necessary that the viscosity ratio of amixture of aqueous components (a) to (c) to a mixture of oil ocmponentscontainig component (d) is 1 or more. The ratio less than 1 unfavorablymakes it impossible to stably incorporate a large amount of the oilcomponents, which causes floating and separating of oils, andfurthermore, undesirable appearance and insufficient performance. Inhair cleansing composition of the invention comprising the abovecomponents (a) to (d), excellent detergency against dirts and mildnessto the scalp and hair fibers are obtained without controlling theviscosity ratio of the aqueous component mixture of (a) to (c) to theoil component mixture containing component (d) if a specificallybranched monoalkyl phosphate and a surfactant having no phosphoricresidue and having a specified solubility are used in combination. Morespecifically, this hair cleansing composition contains the followingcomponents (a-1), (a-2), (b), (c) and (d-1) (hereinafter referred to asa MAP-containing hair cleanser):

(a-1): Salt of monoalkyl phosphate represented by the following formula(I): ##STR1## wherein R represents a β-branched alkyl group having 8 to36 carbon atoms, and X represents an alkali metal, basic amino acid oran organic base;

(a-2): Surfactant having no phosphoric residue and having solubility of1% by weight or more in 25° C. purified water;

(b): Alcohol;

(c): Water; and

(d-1): Silicone oil.

Compounds (I) usable as the above component (a-1) have a branch at theβ-position of the alkyl group. They can be prepared by such methods asdisclosed in Japanese Patent Application Laid-Open to the Public (Kokai)58-180496 and 61-17594. Among the compounds (I), more preferable onesare those of formula (II) having a β-branched alkyl group: ##STR2##wherein k represents an integer of 2 to 18; 1 represents an integer of 2to 14, provided that k+1 makes 4 to 32, preferably 10 to 18; counter ionX is an alkali metal such as lithium, potassium and sodium, basic aminoacid such as arginine, ornithine, lysin and oxylysin, or alkanol amineshaving a hydroxyalkyl group of 2 to 3 carbon atoms such as triethanolamine and monoethanol amine.

Component (a-2) which is a surfactant having no phosphoric residue and asolubility of 1% by weight or more in purified water encompasses all ofthe surfactants defined for component (a) except monoalkyl phosphates.Preferable ones are those having a high hydrophlicity. Examples of thesilicone oil used as component (d-1) are 4 or 5-membered volatile,cyclic silicone compounds, dimethyl polysiloxanes having a viscosity of1 to 1000 cs, and methyl phenyl polysiloxanes having a viscosity of 1000cs or less, preferably 4 or 5-membered dimethyl polysiloxanes, dimethylpolysiloxanes having a viscosity of 100 cs or less, and methyl phenylpolysiloxanes having a viscosity of 100 cs or less.

Preferable proportion of components (a-1) to (d-1) in the MAP-containinghair cleansing composition are 0.05 to 5%, particularly 0.1 to 2% for(a-1); 0.1 to 25%, particularly 0.5 to 5% for (a-2); 0.5 to 40%,particularly 2 to 30% for (b); 0.5 to 50%, particularly 2 to 30% for(c); and 10 to 98%, particularly 50 to 98% for 2 to 30% for (c); and 10to 98%, particularly 50 to 98% for (d-1). If the proportions ofcomponents (a-1), (b) and (c) fall outside the above preferable ranges,lamella liquid crystal or liposome structures cannot be formed, whichmakes it difficult to hold a large amount of silicone oil of component(d-1) stably.

The component (d-1) less than 10% cannot sufficiently liberate dirts ofhair cosmetic products while the same exceeding 98% unfavorably resultsin relatively reduced contents of the other components. The component(a-2) less than 0.1% cannot sufficiently remove dirts by a lot of watertogether with the component (d-1) while the same exceeding 25%unfavorably irritates the scalp and hair fibers.

The MAP-containing hair cleansing composition may further contain anon-siloxane type oil component. This oil component is exemplified bythe non-siloxane type oil components which are defined for the component(d) and are liquid at 25° C. Especially preferred are glycerol diestersof one or two fatty acids such as squalane, 2-ethyl cyclohexane acid,myristic acid, oleic acid, and isostearic acid; glycerol triester of oneor two fatty acids such as 2-ethyl cyclohexane acid, myristic acid,oleic acid, and isostearic acid; octyldodecyl myristate; and isopropylmyristate. These oil components have an action of liberating dirtscooperatively with component (d-1). The proportion of the oil componentsis 50% or less based on the total composition.

In addition to the requisite components mentioned above, the haircleansing composition of the invention including the MAP-containing haircleanser can further contain conventional components such as amoisturizing agent, a blood circulation promoting agent, a coolingagent, a UV absorber or reflector, an anti-sweating agent, a fungicide,a skin activator, an anti-senescence agent, a perfume, and a colorant.

The hair cleansing composition of the invention can be prepared byconventional methods. Especially preferable preparation method is thatfirst the aqueous components (a) to (c) are mixed and agitated to makethem a uniform solution and then the solution is stirred while addingslowly oil components. This process is usually carried out at roomtemperature but may be done while heating the components if they aresolid at room temperature.

The hair cleansing composition of the invention is a transparent ortanslucent uniform gel having a viscosity of 10,000 cs or more at 25° C.It may optionally be added with pigments and/or colorants. It has suchapplications as a shampoo, a preshmpoo; a hair-make remover, a dandruffremover or the like.

The hair cleansing composition of the invention contains a large amountof liquid oil as an O/W emulsion and is a transparent or translucentgel. It is applied onto the scalp or hair fibers, and subsequent massagecan help the oil components quickly spread on the scalp and hair fibers.The spread oil components dissolve or liberate oily dirts accumulated onthe scalp and hair fibers. Then, a lot of water applied for rinsinghelps the oil components containing the dirts self-emulsify to wash themdown. Accordingly, high-viscosity silicone compounds and settingpolymers which are difficult to be removed by conventional shampoos canreadily be removed. Also, it is mild to the scalp and to hair fibers andhas a good feeling upon use.

Further, the hair cleansing composition of this invention has anotherapplication as a conditioner because of a lot of liquid oil containedtherein. It can also readily supply oil-soluble ingredients to the scalpand hair fibers, which have so far been deemed as being difficult to besupplied. Particularly, the MAP-containing hair cleansing compositioncontaining a salt (I) of monoalkyl phosphate is characteristic in thatthe salt (I) forms a lamella liquid crystal structure or a liposome(vesicle) structure together with water and alcohols even at a lowconcentration, and it is considered that the oil components such assilicone oil are retained stably in those structures to form atransparent or translucent, uniform MAP-containing hair cleansingcomposition. Consequently, it can provide an especially excellentproperty to wash out oily dirts on the hair fibers.
